Two-Dimensional Joint Inversion Of ZTEM And MT Plane-Wave EM Data For Near Surface Applications

The performance of two-dimensional (2-D) joint ZTEM/MT inversion was tested using synthetic brick structures below a hill and valley model. Subsequently, separate and joint inversion of coincident ZTEM and Titan dense array MT data over the Johnston Lake district, Saskatchewan, were performed. A result of this effort is that only very few (e.g., three) MT stations may be needed to correct for background resistivity effects in a ZTEM survey provided the MT sites are appropriately spaced.
